A fruit fly experiment starts with 600 flies. If the population increases following exponential growth and there are 1000 flies after 2 days, how many days will it be until there are 10000 flies?
1 000 = 600 e2k
k = .539927
10 000 = 600 e.539927 t where t = days
10 000 / 600 = e .539927 t
t = 5.21 days to 10 000 bugs
